biomimetic method was used to apply hydroxyapatite (ha) coating onto ti6al4v cylinders. this process is a physicochemical method in which a substrate is soaked in a solution simulating the physiological conditions, for a period of time enough to form a desirable layer of the calcium phosphate on the substrate. in the present study, specimens were soaked in 5, 10 m solutions of naoh at temperatu...

4 He/ 3 He apatite thermochronometry and the 13 C-18 O carbonate paleothermometry

The mechanism of cartilage calcification has been outlined in recent reviews."' A study of epiphyseal cartilage calcification has clearly established that the first crystals of apatite that are found in the hypertrophic zone are found in matrix vesicles, in the longitudinal septa.' 2 Matrix vesicles are extracellular, membranous particles, about 100 nm in diameter, that are associated with calc...

Gallstones from three hamsters were studied. The only crystalline material present in detectable amounts was apatite.

The preparation of graphene/apatite and graphene oxide/apatite hybrid nanocomposites has recently attracted great attention in the biomaterial community. sitting drop vapor diffusion technique been assessed as a preparative method for such this work. employed to induce heterogeneous nucleation growth calcium phosphate presence exfoliated commercial oxide flakes, both labeled with L-Alanine. Exf...

Introduction: The magmatic volatiles water, fluorine, and chlorine play critical roles in the physicochemical processes that control thermal stabilities of minerals and melts, magma eruptive processes, and transport of economically important metals. While these volatiles are significant constituents in many terrestrial and martian magmas, lunar magmas are generally depleted in these three volat...

abstractthe purpose of this study was to investigate the controllable operating parameters influence, including ph, solid content, collector, co-collector, and depressant dose, and conditioning time, on apatite flotation kinetics. four first order flotation kinetic models are tested on batch flotation time-recovery profiles. the results of batch flotation tests and the fitting of first-order ki...
